Red Z™ Red Z™ Solidifiers provide state-of-the-art response for spill control and clean-up of potentially biohazardous fluids. The encapsulation technology captures and immobilizes fluid activity up to 100 times it weight. The high "AUL" (absorbency under load) prevents fluids from leaking out, preventing aerosolization, reducing the risk of cross-contamination. Simply sprinkle onto a spill, and within seconds, the fluid will solidify into a granulated gel.
